Here is my site. I tried the suggestions in this topic before starting my own thread. I am using the Crisp Persona theme, and would like to try to remove the word "by" with the Show/Hide Author plugin before going in to fiddle with a child theme.
Inspecting the block of code that yields "by Seetha Sankaranarayan" with Firebug, here is what I get:
<span class="byline"> by <span class="author vcard"> <a class="url fn n" href="http://seethasankaranarayan.com/author/seethasankaranarayanc/" title="About Seetha Sankaranarayan" rel="author">Seetha Sankaranarayan</a> </span>
For the field "The parent classes" I entered "byline" and that seemed to work in removing "Seetha Sankaranarayan". I've tried several different options for the field "The regular expressions" but nothing seems to be working. Any suggestions?
